A malicious software program known as Conficker that many feared would wreak havoc on April 1 is slowly being activated, weeks after being dismissed as a false alarm, security experts said.
Conficker, also known as Downadup or Kido, is quietly turning thousands of personal computers into servers of e-mail spam and installing spyware, they said.
The worm started spreading late last year, infecting millions of computers and turning them into "slaves" that respond to commands sent from a remote server that effectively controls an army of computers known as a botnet.
Its unidentified creators started using those machines for criminal purposes in recent weeks by loading more malicious software onto a small percentage of computers under their control, said Vincent Weafer, a vice president with Symantec Security Response, the research arm of the world's largest security software maker, Symantec Corp.
"Expect this to be long-term, slowly changing," he said of the worm. "It's not going to be fast, aggressive."
Conficker installs a second virus, known as Waledac, that sends out e-mail spam along with a fake anti-spyware program, Weafer said.
"This is probably one of the most sophisticated botnets on the planet," said Paul Ferguson from Trend Micro Inc, a security software maker.
